Contrary to popular belief coyotes don't howl at the moon- full or otherwise. Coyotes will "sing" morning or evening. Despite its lonely sound, the coyote’ howl is a form of communication. Scientists who have listened to the songs of coyotes believe that howling is the coyote's way of keeping strange coyotes out of its territory, as well as keeping in touch with other members of the coyote family. Coyotes sometimes call other coyotes to hunt or eat food Coyotes also squeal, bark, yip and yowl. All these sounds have special meanings to coyotes.
